-proteins that are being exported (secreted) out of the cell comes here - one side receives (cis) and ships out (trans)
- flattened membrane sacs
3
Q
vesicles
A
- packaging
-transports materials around the cell - keeps dangerous materials contained
- made of phospholipids
4
Q
mitocondria
A
powerhouse of the cell
creates ATP
double membrane
own circular chromosome
Makes own ribosomes
syn their own proteins

found in plants and fungi
storage
chemical defence chemicals
